Omental pregnancy is a rare form of abdominal pregnancy. In the 5 previously reported cases, primary implantation of the embryo to the omentum has been proposed as its etiology. We present a new case of omental pregnancy in a 31-year-old woman presenting with symptoms of ectopic pregnancy. After careful review of our case and the published literature in view of the accepted definition of primary abdominal pregnancy, we conclude that all reported instances of omental pregnancy are secondary and probably follow tubal or ovarian pregnancy abortion.
大网膜妊娠是腹内妊娠的一种罕见形式。在先前报道的5例病例中，胚胎原发性植入大网膜被认为是其病因。我们报告一例31岁女性大网膜妊娠的新病例，该患者表现出异位妊娠的症状。鉴于原发性腹内妊娠的公认定义，在仔细研究我们的病例和已发表的文献后，我们得出结论，所有报道的大网膜妊娠病例均为继发性，可能继发于输卵管妊娠或卵巢妊娠流产。
